Volume 4 of the series "The Man in the Ice" contains the latest scientific results about the Iceman. By means of different methods - e.g. AMS-radiocarbon dating, bryology, dendrology, etc. - the reader gets information about several aspects of the Iceman's lifestyle and his natural environment. His artefacts give insight into prehistoric craftsmenship. Even the potential location of his settlement is reconstructed by several different approaches. The good preservation of the pollen in his food residue allowed to identify the season when the Iceman died. Detailed pollenanalyses of mire deposits in the alpine region of the Ötztal gave insight into the genesis of the alpine grass heath and early pastoral farming of a time long before the Iceman lived. Radiocarbondating of a piece of wood from the Iceman's finding spot demonstrates the early interest of prehistoric people in these highland zones. But also perspectives of future research activities are given.
